    摘要： Techniques are provided that can extend the efficiency of a switching regulator further into the low current region by making use of the available knowledge on predictable load variations and voltage ripple tolerance across different states, providing improved efficiency and reducing total current consumption. The load current requirement in low power states is provided using switch mode rather than linear regulation, the switch mode operation being controlled by a mode dependent control circuit so as to minimize the energy cost of the switching operation in each mode and thus obtain improved efficiency from the power source.

    摘要： Techniques are provided aimed at improving the flexibility and reducing the area and power consumption of digital baseband integrated circuits by using stream data processor based modem architecture. Semiconductor companies offering baseband ICs for handsets, face the challenges of improving die size efficiency, power efficiency, performance, time to market, and coping with evolving standards. Software defined radio based implementations offer a fast time to market. Dedicated hardware designs give the best die size and power efficiency. To combine the advantages of dedicated hardware with the advantages of conventional software defined radio solutions the stream data processor is partitioned into a stream processor unit, which implements processing functions in dedicated hardware and is hence die size and power efficient, and a flexible stream control unit which may be software defined to minimize the time to market of the product.

The clock generating circuit generates a sampling clock signal, a phase-early sampling clock signal and a phase-late sampling clock signal. The receiving circuit samples received data according to the sampling clock signal, the phase-early sampling clock signal and the phase-late sampling clock signal to generate a sample result. The training circuit controls the clock generating circuit to generate the sampling clock signal and the corresponding phase-early sampling clock signal and phase-late sampling clock signal that have different phases in a plurality of different time intervals, respectively, to cause the receiving circuit to generate a plurality of sample results. The training circuit further determines a sampling phase of the sampling clock signal according to the sample results.

    摘要： A display apparatus includes a video processor, a graphics processor, a combining circuit, a retrieving circuit and a graphics controller. The video processor process target video information and generates a corresponding video signal. The graphics processor processes graphic data and generates a corresponding graphic signal. When the target video data changes from first video data to second video data, the retrieving circuit retrieves a static picture associated with the first video data and accordingly generates a retrieval result. The graphics controller utilizes the retrieval result as graphic data provided to the graphics processor. The combining circuit combines the graphic signal on the video signal to generate an output video signal.
